How do you know that someone has that love in their life?"
No my question was and still is how do you or anyone know whether someone has faith in Jesus ?
Lots of people talk about love, unfortunately they rarely calerify what they mean by love or what they are loving.
There are even people who claim to love God/Jesus but without obeying him.
Jesus did not talk about loving him, he talked about belief, who ever believes in me has eternal life.
James interestingly gets right to the heart of this.
He say show me your faith ( or love ) I by my works ( obedience ) will show you my faith.
I will answer my question for you.
Jesus says if you love me you Will Obey my Commands.
We know someone has faith in Jesus as their Saviour because they seek to obey him.
Someone can prattle about love, but if there life does not show practical change and striving to follow Jesus then there words are just that words.
